Frequently Asked Questions
Q: What specialized environments is the CR 310077 designed for?
A: The CR 310077 is specifically engineered for heavy-duty applications and freezer environments. The 83A polyurethane compound with compound 201 formulation maintains traction and durability in cold storage temperatures where softer compounds become too rigid or too soft. This makes it ideal for frozen food warehouses and cold chain logistics operations.
Q: What are the dimensions and bearing specifications for the CR 310077?
A: The CR 310077 measures 3.25 inches in diameter and 5.88 inches in tread width. The bearing bore is 2.047 inches, compatible with standard Crown electric lift truck bearing assemblies. These dimensions support heavy static and dynamic loads common in industrial freezer applications.
Q: Why does the CR 310077 use 83A hardness instead of a higher durometer rating?
A: The 83A durometer formulation is intentionally softer than standard load wheels to maintain grip and flexibility in cold storage temperatures. In freezer environments below 32 degrees Fahrenheit, harder compounds become brittle and lose traction. The 83A compound 201 formulation preserves elasticity and grip performance in extreme cold while resisting wear under heavy loads.
Q: Can the CR 310077 be used in non-freezer applications or on warm floors?
A: While the CR 310077 can technically be used in warmer environments, it is not optimal for standard ambient-temperature applications. The softer 83A compound may wear faster at higher temperatures and in non-freezer duty. For ambient warehouse operations, consider standard 95A or 97A compound wheels instead. Use the CR 310077 exclusively for freezer and heavy-duty cold storage applications to maximize part lifespan.
